OPHTHALMIC MOUNTING.

Application filed November 22; 1922.

To all whom it may concern:

Be it known that I, EARLE J. R. BEATTEY, a citizen of the United States,and a resident of Providence, in the county of Providence and State ofRhode Island, have invented a new and useful Improvement in OphthalmicMountings, of which the following is a specification.

The present invention relates to ophthalmic mountings, and moreparticularly to nose guards. The object of the invention is to provide anose guard constituted of nonmetallic material that shall have a moresecure gripping action than is obtainable withguards of this type atpresent in use.

The invention is illustrated in the accompanying drawings in connection,with an Oxford mounting shown in Fig. 1; Fig.- 2 is an enlarged view ofa guard constructed according to a preferred embodiment of the presentinvention, shown attached to a lensreceiving rim; Fig. 3 is a sectiontaken upon the line 33 of Fig. 2, looking in the direction of thearrows; and Fig. 4 is a view of a preferred gripping insert, prior toits incorporation into the guard.

Metal guards are not very difiicult to deal with, because they can bereadily bent, with pliers, to conform exactly to the shape of the nose.Guards constituted of non-metallic material, like celluloid, zyloniteand shell, can not be adjusted in this manner, with the consequence thateither they happen to fit properly, or else they do not hold verysecurely in place. This is particularly true of guards like thoseillustrated at 2, provided upon the lens-receiving rims 4 that areintegrally connected by a resilient bridge 6 of the Oxford type ofophthalmic mounting. Each guard 2 is constituted of a small sheet ofnon-metallic material, and is cemented or otherwise integrally securedto a rim 4' along an edge 8 of the guard, so as to be flush with thefront face of the rim. The guard is provided with a comparatively largegripping face, as shown. It will seldom happen, therefore, that it willconform exactly to the nose of the wearer, so that portions will engagethe nose, and portions will not, with the result that a very insecuregrip is obtained upon the sides of the nose.

It is found that a much more secure gripping effect will be obtained byproviding.

the guard with an additional gripping ma- Serial No. 602,622.

terial, like sharks skin. To retain the pleasing appearance of thenon-metallic material, the sharks skin is applied to but a comparativelysmall portion of the guard, in a comparatively small recess 10. To holdthe sharks skin in place, the recess may bebevelled, as shown at 12,Fig. 3, and the small sheet ofsharks skin may be correspondinglybeveled, as shown at 14. The sharks skin is in this manner very easilysecured in place in the recess, substantially flush with the face of theguard, and it is effectively retained in place by the beveled walls 12.

It will be obvious that the invention is not. restricted to the exactembodiment thereof that is herein illustrated and described, but thatitmay be modified by persons skilled in the art. tions are considered tobe within the spirit and scope of the invention, as defined in theappended claims.

lVhat is claimed is:

1. A guard for an ophthalmic mounting comprising a sheet of'non-metallicmaterial having a gripping face provided with a recess, and additionalgripping material in the recess, the additional gripping material beingof different character from the nonmetallic material of the sheet tofacilitate gripping action.

2. A guard for an ophthalmic mounting comprising a sheet of non-metallicmaterial having a comparatively large gripping face provided with acomparatively small recess, and an additional sheet of gripping materialseated in the recess substantially flush with the gripping face of theguard, the ad ditional gripping material being of different characterfrom the non-metallic material of the sheet to facilitate grippingaction.

3. An ophthalmic mounting comprising a lens-receiving rim and a guardintegrally connected together along an edge of the guard and constitutedof non-metallic material, the guard having a gripping face provided witha recess, and additional gripping material in the recess, the additionalgripping material being of different charactor from the non-metallicmaterial of the guard to facilitate gripping action.

4:. An ophthalmic mounting having, in combination, two lens-receivingrims, a bridge connecting the rims, and a guard connected to each rimalong an edge of the Such modificaguard, and all integrally connectedtogether and constituted of non-metallic material, each guard comprisinga sheet of nonmetallic material having a comparatively large grippingface provided with a comparatively small recess, and an additional sheetof gripping material seated in the recess of each guard substantiallyflush with the gripping face of the guard, the additional grippingmaterial being of different character from the non-metallic material ofthe sleet to facilitate gripping action.

A guard for an ophthalmic mounting having a gripping race provided Witha recess the Walls of which are bevelled, and an additional sheet of griaping material retained in the recess by the bevelled Walls, theadditional ripping material being oi' diil'erent charm/L r from thenon-metallic material of the guard to facilitate gripping action.

6. A guard for an ophthalmic mounting comprising a sheet of non-metallicmaterial having a gripping l ace provided With a llat-bottoi red recessthe Walls of Which are bevelled inwardly -from the flat bottom towardsthe ipping face, and an additionsheet of gripping material seated in therecess in contact With the flat bottom and substantially flush with thegripping face,

the additional gripping material being retained in the recess by thebevelled Walls, and being of different character from the nonmetallicmaterial of the sheet to facilitate gripping action.

7. An ophthalmic mounting having, in combination, tWo lens-receivingrims and a bridge connecting the rims disposed in sub stantially acommon plane, and tWo guards, the rims, the bridge and the guards beingall integrally connected together and constituted of non-metallicmate-rial, each guard comprising a sheet of non-metallic materialconnected to a rim an edge of the d and extending beyond the plane of herims to provide a comparativeiy lar e gripping face, each sheet beingprovided With a com-par rely small recess, and an additienal SllGQro-igripping material seated n the recess of each guard substantially flushWith the gripping face of the guard, the additional gripping material boi different character from the non- -erial oi the guard sheet tofagripping action. stimony thereof, 1 have hereunto subscribed my namethis 16th day of Nd vember, 1922.
